m-ACR 7601
16 AWG
• These installation diagrams show typical applications only. Your application may differ.
For further information, please go to www.bluesea.com and navigate to Resources/Application Briefs
and Technical Briefs.
• Because the m-ACR is dual sensing, the battery connection terminals are interchangeable.
m-ACR function will not be affected by reversal of the starting and house batteries versus the diagram.
•IfthestatusindicatorLEDistriple-ashing,them-ACR is in a lockout state, and will not combine
batteries until the lockout condition is removed. Ensure neither battery is below 10V for a 12V system
or 20V for a 24V system.
•IfthestatusindicatorLEDisdouble-ashing,checkforpositivevoltageonthestartisolationterminal.
• It is recommended that the m-ACR be connected directly to your battery positive terminals through
appropriately sized fuses. Connecting in a different location such as a battery switch may affect
accuracy because of voltage drop along current carrying conductors.
• If you are not knowledgeable about marine electrical systems,
please consult an electrical professional for help with installation.
• Ifyourelectricalsystemisconguredwithachargingsourcethatcannotsupply
the full load current being drawn from the batteries, open/close cycling
can occur. If this cycling continues, the second battery bank
could eventually discharge even though a charge source is present.
See Wire Size and Fuse Rating chart for connections from ACR positive terminals.
